The space infrastructure will have to be provided by institutional funding as revenues from this venture will not be able to pay for this. Initially, the ground segment will have to be provided by the same funding source, but the revenues produced from the sale of power will lead to the privatisation of operation and hence the use of private funding sources. Full Scale Power Delivery (Budgetry Requirement $23BN) The next step in the evolution of the SSPP staged plan is the transition to 5GW space power stations providing constant power to the electricity grids. The revenues generated by such ventures are substantial and will present a major source of stable cash inflow to the company. The funding for space infrastructure is large and will require either full or partial institutional financial backing. However the large cash inflows during operation allow more of the program to become commercially viable and hence able to use private sources of finance. The hybrid funding structure of the ISPO organisation will move away from institutional backing to private sources of finance as hte operation expands and revenues continue to increase. Space to Space Solar Power Demonstration 1 The first demonstration of space to space beamed power is a technology demonstration exercise. This demonstration has a very low budget ($ 80M) and would be funded by any one of the major space agency budgets. International cooperation could be applied to show this approach to program management and build the future for further cooperation on larger scale projects. Demonstration 2 The second space to space power beaming demonstration is to beam laser power to existing solar arrays in space. This is again a technology demonstration in the first instance, but a market for this kind of power supply has been identified so commercial benefits could be envisaged at this stage. These early commercial benefits from space to space beamed power, for eample extending the life of commercial communications satellite, could provide a limited source of cash inflow. However these demonstration exercises will probably be supplied free of charge to cultivate this market area and generate a potential customer base. First-Business Applications First business applications of space to space beamed power use a custom satellite to beam several kilo watts of power to multiple satellites. This could generate significant cash inflows from this venture. Initially a government supported venture such as the french SPOT company would be required to establish the required space infrastructure. This project could become commercially viable if potential customers can be convinced of the reliability and cost effectiveness of this method of power supply. Mid-term Applications Mid term applications of space to space solar power will use several custom satellites to povide several tens of kilo watts to users in all orbits and on the moon. As the market has been developed there will be significatnt cash inflows from this venture which should be commercially viable. This will allow all space infrastructure and operating costs to be met by private sector financing. 11.3.1 Financial Revenue Forecasts This section of the SSPP report will consider the possible revenues that will be obtained during the implementation of the SSPP financial plan and show how these vary with the global cost of energy. The correlation between the system costs and revenues obtained, along with a simple sensitivity analysis, will also be presented. Results of space to space revenue forecasts are given in section 11.1.2.
